Ms Mosse-Brown said she spent much of her life cutting sugarcane in the fields around her home and attended church regularly.
On Saturday (AEST), the news flashed around the world on in seconds that the world's oldest person had died at the age of 117 years and 38 days in her Jamaica home.
Brown was somewhat of a celebrity in Jamaica, after receiving visits from Prime Minister Andrew Holness, Governor General Sir Patrick Allen and other prominent leaders in the community.
A close family member of the supercentenarian told LOOP NEWS that after a brief illness, Moss Brown died at the Fairfield Medical Centre in Montego Bay, where she was recently taken by family members. She died on August 4, 1997, at the age of 122 years and 164 days.
"I was a cane farmer".
She added her "faith in serving God, and believing strongly in the teaching of the bible" were also fundamental to a long and healthy life.
"I've done almost everything at the church. I worked, me and my husband, over that hill". She became the oldest living person on April 15, 2017, following the death of Emma Morano who was 117 years and 137 days.
Asked what was the secret to long life, she replied that eating cows feet, not drinking rum and reading the bible were key.
"Eat and sleep and you will live a long time", she said, adding: "You have to learn to relax".
